Windows kernel extracts various BIOS information at boot-time.
The method it uses to extract SystemBiosDate & SystemBiosVersion which
are then stored in:
* "HKLM\HARDWARE\DESCRIPTION\System" "SystemBiosDate"
* "HKLM\HARDWARE\DESCRIPTION\System" "SystemBiosVersion"
is very hueristic and depends on data contained in the BIOS's data
section.
The implementation resides in:
* nt!CmpGetBiosVersion()
* nt!CmpGetBiosDate()
respectively.
For reference implementation, see ReactOS:

This patch series aims to make SeaBIOS's data section interact better
with the Windows OS and report correct date & version values.
Liran Alon (4):
bios_date: Make all dates in BIOS consistent
bios_date: Make bios date appear once in the ROM
bios_date: Change BiosDate to SMBIOS bios date
bios_version: Remove misinterpreted version string
Sam Eiderman (2):
bios_date: Add bios date checks in checkrom.py
bios_version: Add bios version checks in checkrom.py
